StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 26 June 2026; the live site may have changed since.

Gründo — Duolingo for entrepreneurs is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 26, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 weeks before launch. Our crawler found 6 technologies on this site, covering animation, DNS providers, web fonts, and hosting. The stack includes cdnjs, GoDaddy DNS, and Google Fonts.

Notably, it's on one of the most common stacks we track, shared by 2,326 launches.
